[Roki123]

so I have a GIGABAYTTE motherboard GA-B85M-D3V PLUS-SI and when I try to turn it on, the fans work and the led lights light up, but the picture doesn't show, I tried to reset it, I changed the ram, I reset the coms, I even changed the other processor to make sure the motherboard is new, I haven't been able to turn it on yet when I tried to turn it on, I had this problem, I would be very grateful if someone could help me
